I've heard of issues on all repops, a body man advised me to save my originals if i can being that all repops are not the greatest. The lines are not as crisp, long or short fenders/quarters. One other guy that I bought some parts from was restoring a Mustang had to cut a half inch from the back end of a quarter to fit properly. While in Denver I stopped by this shop while they were restoring a 69 Firebird and guy had brought new fenders and a quarter so they can finish up his car and they told him he wasted his money because they would rather work with original sheetmetal. Good luck on your quarters.
